PATENT oFF-ICE NEW YORK, A CORPORATION or N W YORK ROT RY ertizzLY Application filed Ap1'i1 8,

This invention relates toa rotary grizzly of the general type comprising a series of disc-carrying shafts, the openings formed like material as of the shafts. 1 v 1 One object of the invention is to provide a rugged and substantial arrangementof gearing between the power unit and the disc-carrying shafts, such that the machine will stand up and give eflicient service for excessive strain and wear to which it is sub jected, while also making provision for driving the shafts at different speeds.

A further purpose of theinvention isto I afford asimplified arrangement of gearing and efficient means for assuring lubrication of all wearing"parts of the gearlng and bearings.

To these and other ends,' th'e invention consists in the form and arrangement of parts that will appear clearlyffrom'the following description whenread in conjunc- -t1on with the accompany ng draw1ngs,-the

novel features being pointed out 'in the claims following the specification. In the drawings: 7

The'invention maybe carried out in a variety of "ways, and as an example of one practlcal adaptation, there is here disclosed a structure comprls ng a serles of d sc-car-o rying shafts 1, of which there may be any desired number, each provided with a disc 2 and forming the openings 3'throu'gh which view taken 192?.

material is separated, as usual in accord with this type'of machine.

The shafts 1 turn in bearings 4L forming part of a housing 5. The customary practic'e is to drive the disc-carrying shaft at the feed end of. the machineat a minimum.

rate of'speed and the disc-carrying shaft at. the discharge end of the machine at a of travel of the disc-carrying shafts by gearing of simple construction and with m'ax1mum wearing qualities. The parts are lntended tojbring now to be described this about. 7 I V t .7

Each disc-carrying shaft *1 has keyed; thereon at its outer enda wormjgear 6 that is engaged by a worm 7'slidably keyed on the driving shaft '8, so as to be fixed against" relative rotation thereon and to have lon- 1 gitudinal play, the end thrust of each worm stantly increasing speed of'the disc-carrying shafts is had as'the discharge endof the machine is approached. This arrangement affords a most rugged and durable driving gearing for a machine of this character, and it isequally important that adequate lubrication be insured to every part of the gear'-' ing at all times. This is accomplished in the following manner. I

The worm gears 6 rotate in a chamber formed in the housing 5 bymeans'oftheouter side wall-l0 and endwalls-lLo'fthe. housing 5 and said chamber is divided into:

pockets by means of transverse overflow each engaging one of, the aforementioned worm gears, and a series of bearings located within said housing for the drive shaft, one

of such bearings being located between the ends of each two adjacent worms and acting to receive the end thrust of one of said worms.

6. The combination with a series of adjacently arranged parallel shafts, of a lubricant-containing housing having a side wall, a series of bearings formed in said side wall for the aforementioned shafts, a worm gear mounted on each shaft within said housing, a drive shaft located within the housing above the worm gears and extending transversely of the first mentioned shafts, a series of worms slidably keyed on the drive shaft and each engaging one of the aforementioned worm gears, and a series of bearings for the drive shaft located within said housing, one ofsaid bearings being arranged
